Portuguese here. Speed cameras are definitely legal, although it's mandatory to have a sign indicating their presence x meters beforehand (if I'm not mistaken). Also mobile police units with speed cameras in very discreet places is a common thing. What happened in Lisbon some time ago though was that most of the radars ended up dying due to lack of maintenance (due to lack of funds/attention/whatever). A lot were recently reactivated I heard.
But yeah these speed sensitive red lights are common and I agree that they work pretty well. Social pressure is good for behavioral nudging. Reminds me of those led signs that show a sad face if you go over the limit on certain residential areas for example.
However I must say that nothing beats Belgium in speed radars. Especially in Flanders, there are so many of these damn Gatso speed traps... What really makes the whole thing work though is a very good system behind it. Here in Belgium, if you're caught by a speed camera, you'll get the fine within 2 weeks tops. In Portugal however you might not even get it because the pile of fines to process is too big and the system isn't prepared for it.
I can confirm the roundabout obsession too :) those can be really annoying but they sure slow people down.
Great stuff, I've been using iTerm2 for a while and it's really good to see it evolve like this.
I use screen a lot (yes I know, I should switch to tmux one day!) and shell integration doesn't seem to work properly with sessions inside screen. Works perfectly if I ssh directly. Is it going to be supported eventually or is this the ultimate signal for me to switch to tmux?
As someone responsible for search on a yellow pages company, I can confirm that most YP websites have little to no protection against this. Company information is usually public anyway. We just make it very easy for you to get it :)
